Does anyone know of a way to use a variable as the filename input into xlsread?

Question

EDIT: I figured out the problem. claim was listed as a cell class. Used cell2mat to convert it to char, and the code worked. Thank you, everybody!

I have a string variable set to a file pathway/location. I would like to use this variable as the input to the xlsread function, but Matlab tells me that xlsread cannot take a variable input. I'm having lots of trouble figuring whether a workaround is even possible. Can someone help me out?

 function C = claimReader()

 inp = csv2struct(['C:\Documents and Settings\nkulczy\My Documents\085 Starry Sky\','Starry_Sky_inputs_vert.csv']);
 inputTitles = [{'Output_Dir'};{'Claimz'};{'Prodz'};{'Fault_Locations'};{'Fault_Type'};{'Primary_Failed_Part'};{'Part_Group'};{'Selected_SEAG'};{'Change_Point'};{'Date_Compile'};{'Minimum_Date'}];

 claim = inp.(cell2mat(inputTitles(2)));  %returns a file path/location string

 C = csv2struct(claim);

 end


 function Out = csv2struct(filename)

 %% read xls file with a single header row

 [~, ~, raw] = xlsread(filename);

 [~ , ~, ext] = fileparts(filename);

 if ~strcmpi(ext, '.csv') %convert non .csv files to .csv, so blanks stay blank
      filename=[pwd,'tempcsv',datestr(now,'yymmddHHMMSSFFF'),'.csv'];
      xlswrite(filename,raw);
      [~ , ~, raw] = xlsread(filename);
      delete(filename);
 end

 if size(raw,1)==11 && size(raw,2)==2 %transpose SS inputs (must      match dimensions of input matrix EXACTLY!!!)
     raw = raw';
 end

 nRow = size(raw,1);
 nCol = size(raw,2);
 header = raw(1,:);
 raw(1,:) = [];

 end

Answer 1

Use the syntax as following and there shouldn't be any problems:

pathname = 'c:\...\filename.xlsx';
A = xlsread(pathname);

Edit: regarding your code:

I can't see where you define filename - you should pass claim (it contains the desired path?) to the xlsread-function. Probably you get a cell with chars. So your input needs to be claim{1}

Answer 2

Check the documentation of xlsread, the first output (yourNums) will only return the numerical values in the sheet. txt will only return text. rawData will return the raw data in the sheet.

flNm = 'c:\myFolder\myFile.xlsx';

[yourNums, txt, rawData] = xlsread(flNm);

Update after TS:

claim is a cell array. So you need to pass claim{1} in order to let it be a string.
